2、t and dock bulk material.Bucket elevator for vertical lifting through the crusher limestone, coal, gypsum, clinker, dry clay block granular material as well as raw material, cement, coal and other powder materials. According to the different speed of hopper, the bucket elevator can be divided into t
3、hree types: centrifugal discharge, gravity discharge and mixed type discharge. Centrifugal type unloading material bucket speed faster, for conveying powdery, granular and small shape grinding material cut small; gravity discharge material slow speed of the bucket for bulk transport, the proportion
4、of larger, grinding Zhuo materials, such as limestone, clinker, etc. The traction component of the bucket elevator has several kinds of chain, plate chain and adhesive tape. Ring chain structure and manufacture of relatively simple, is also very strong connection with the hopper, conveyor mill Zhuo
5、of material, wear a small chain, but the larger self. Chain plate structure of a solid, lighter weight, applicable to a large quantity of hoist lifting, but articulated joint is easy to wear out, the tape has the advantages of simple structure, but not suitable conveyor mill cut large materials, the
6、 ordinary belt material temperature does not exceed 60 DEG C, steel cord belt clip allows the temperature of the material up to 80 DEG C, heat-resistant tape allows material temperature of 120 DEG C, ring chain, plate chain conveying material temperature of up to 250 DEG.Scope of applicationThis ser
7、ies bucket elevator is suitable for conveying powdery, granular and small shape of grinding Zhuo and grinding Zhuo small materials, such as coal, cement, stone, sand, clay, iron ore and other, because the elevator traction mechanism is a circular chain, thus allowing transport of high temperature ma

22、ng and a driving device.Installation and maintenanceMachine maintenance is a very important regular work, it should work closely with the operation and maintenance, and should have full-time personnel on duty check.BearingAll the load bearing 1. Crusher assume a machine, so good lubrication on beari
23、ng life have great relationship. It directly affects the machine life and the operation rate, therefore require the injection of a lubricating oil must be clean, seal must be in good condition and main oiling the machine of a rotating bearing, roller bearing the all gear and bearing, sliding plane.2
24、 the installation of the new tyre must be examined often prone to loose.3 pay attention to the work of each part of the machine is normal.4 pay attention to check the wear degree of easy to wear parts, always pay attention to replace worn parts.5. The plane of the bottom of movable device, should go
25、 out dust and other matter lest machine can not meet the broken material bearing activities can not on the underframe mobile, resulting in serious accidents.6 increase the bearing oil temperature, should stop and check the reason to be eliminated.7 when the rotation of the gear in operation if there
26、 is an impact sound should be immediately stopped to check and eliminate.Installation commissioning1 the equipment should be installed in the level of concrete foundation, fixed with anchor bolts.2 attention should be paid to the installation of the vertical and horizontal.3 after installation, chec

So
31、every time before the machine should be discharged in all the hopper of the material, and then stop.2 can not be reversed. Reverse the chain derailment that may occur, to eliminate the trouble of derailment.3 uniform feeding. The sudden increase of the volume of feed ban. The feeding amount can not
32、exceed the capacity of lifting and conveying machine. Otherwise, it is easy to cause the bottom of the accumulation of serious stuffy car accident.4 timely and proper amount of lubricating oil.5 the chain and the hopper should be replaced in a timely manner when severe wear or damage.fault analysisf
33、aultTo enhance the head wheel and the bottom wheel shaft mounting is not likely to cause the hopper belt deviation, main forms: the head wheel and the bottom wheel transmission shaft in the same vertical plane and is not parallel; two driving shafts are installed in a horizontal position and in the
34、same vertical plane; the two transmission axis parallel and in the same vertical plane and horizontal. Such a situation, the hopper belt deviation, easy to cause the hopper and barrel hit, hopper with tear. In addition, the head of the hoist can bear large dynamic pressure, the maximum amount of up
35、to 100 tons, due to the long operation of the inevitable in the bearing wear.Traditional methods to repair welding or brush plating machine repair, but both of them are some drawbacks: repair welding of high temperature of the thermal stress can not be completely eliminated, easy to cause material i
36、njury, leading to bend or break components; and brush plating coating thickness, is easy to peel and the above two methods are with repair of metal metal, can not change the hard to hard with the relationship between, in under the influence of the force, still caused by wear again.In view of the abo
